How to best connect a tether to your harness?

Have you ever heard some version of this?

“You should NEVER connect your tether/PAS to your belay loop. Todd Skinner did that, his belay loop broke, and he died. So, you shouldn't do it either.”

or maybe:

“You should ALWAYS run soft goods, like rope and slings, through the tie in points, and clip hard goods, like carabiners, to the belay loop.”


I’ll start off with my opinion on this, right up front: I think, in most cases, it’s fine to attach a tether to your belay loop. 

There are a lot of people who feel differently, and if you prefer your tie in points for a tether, that’s great.  But know that in most cases, your belay loop is going to work fine as well. There are very few black and white, “Should”, “Always” and “Never”, “Gotta do it this way or else” rules in climbing. This is not one of them.


Here's what IFMGA guide Dave Searle thinks about it, and I agree!


When ascending a route, it's usually best practice to use the rope and clove hitch yourself to the anchor. But when it's time to rappel, you're probably going to want a tether. Whether you use a designated tether like a PAS or a Petzl Connect, or make one DIY with a double length sling, or you’re an aid climber and have a pair of daisy chains, you need to choose where to connect it to your harness - belay loop or tie in points?

The truth is . . . it depends! There are some cases when attaching your tether directly to your belay loop is not only acceptable, but the recommended practice. There are some other situations where it's probably not such a great idea.

  • What kind of climbing (rappelling, big walls, via ferrata) are you doing?

  • What does the manufacturer say?

  • What’s your tether made of?

  • What kind of knot or hitch connects the tether to your harness?

These are all nuances in technique that need to be considered, rather than a binary “always” or “never.”

Alpinesavvy tries to offer ideas and information, not advice. So, read on and make up your own mind.


Here are some general guidelines and considerations:

  • First, and perhaps most important, check your harness regularly and retire it without hesitation if it shows significant wear for any reason.

  • If you do connect a tether to your belay loop, don’t leave it tied there permanently. Doing this can prevent the loop from rotating and may concentrate wear in a single spot. Remove the tether when you're done for the day, or after your rappel.

  • If you're girth hitching a designated PAS type tether, the usual manufacturer recommendation is to use both tie in points. (Even then it's a bit of a “soft” recommendation, see below.)

  • If you're girth hitching a “DIY” tether with a skinny Dyneema sling, it’s probably best to use both tie in points. (Should you use a use a Dyneema sling as a tether at all? See the “expert photo” section below.)

  • If you're girth hitching a tether (or adjustable daisy for aid climbing) with a wider nylon sling, either the tie in points or the belay loop should be fine.

  • If you're using a rope style lanyard such as the Petzl Connect Adjust, follow Petzl’s recommendation and girth hitch it to your belay loop.

  • If you’re doing via ferrata, the standard practice is to girth hitch the lanyards to your belay loop.

  • If you're big wall / aid climbing, the tie in points are usually better, because that gets your waist a bit closer to the gear you're clipped to. Every inch helps!

  • And . . . if you're not using a girth hitch and using a double loop bowline tether, it's okay to tie it through your belay loop with any kind of material.


What are some of the pros and cons of attaching a tether to your belay loop?

Pros:

  • Comfort. Having a weighted tether girth hitched through your tie in points can cause your harness to squish together on some, shall we say, sensitive body parts, ouch! This depends a bit on the design of your harness and ahem, personal anatomy, your mileage may vary. This can be especially true for women with wider hips and a higher waist.

  • Easier to rig and check. For cold weather climbing with bulky clothing, gloves, etc., it can be easier to properly thread your tether through your belay loop, as well as glance down and be sure it's threaded correctly. (This goes for checking your partner also.) Plus, the comfort factor: with more clothing on, tethering to the belay loop will usually be more comfortable.

  • More reach. If you have a shorter tether and you’re a taller climber, having it on your belay loop can give you a few extra inches of reach.

  • Less cluster. This probably applies more to big wall climbing, when the front of your harness can get very busy with two daisies, fifi hook(s), rope tie in, etc. Using your belay loop can spread out these connections a bit. Also for big wall climbing, you’re probably sleeping in your harness as well, so a belay loop connection will typically be more comfortable.

Cons:

  • Not redundant. You're connected to one point of your harness while you could be connected to two. (This introduces a whole other conversation of all of the other non-redundant components in the climbing system you rely on the time, but let's save that for another discussion.)

  • Puts extra wear and tear on your belay loop. (This argument may be countered by pointing out that the wear and tear is not eliminated, but instead transferred to your tie in points.)


Let's look at some more specific cases of where to attach your tether.

First, let's check out recommendations from Black Diamond. Their website tells you that girth hitching a daisy chain through both tie in points gives you the “green check” of approval. End of discussion, right?

Well maybe not. Using the bottom tie in point is clearly a no-no, because it might flip you upside down. But the belay loop or the top tie in merits only the orange “caution” notification, not the red skull and crossbones, “Yer Gonna Die”.

What else gets the Black Diamond orange caution? Getting your tether wet, icy, or dirty! Sheesh, we all know that happens to your gear all the time and it's hardly the end of the world. So, attaching a tether to your belay loop is in the same category of “it's best to avoid doing this a lot, but if you do, it's not going to be catastrophic.”

Let’s consider the following . . .


1 - No warnings from harness manufacturers

The Alpinesavvy web gnomes looked carefully at the technical documentation for harnesses from Black Diamond, Petzl, and Edelrid. None of these manufacturers give a warning against attaching a tether to the belay loop. If doing so is “wrong”, do you think the top harness manufacturers might warn against it in their technical documentation?


2 - Petzl Connect Adjust, Beal Dynaconnexion, CAMP Swing, and Edelrid Switch: use the belay loop

In 2015 Petzl introduced their “Connect”series of lanyards. These are made from dynamic climbing rope, and have a stitched, fixed loop at one end. It's a pretty sweet piece of gear.

Petzl recommends girth hitching it to your belay loop, as shown in this illustration from their website.

Let's check out another nice diagram from Petzl.

1. Where do I attach my lanyard?

“From a safety and strength perspective, the lanyard can be attached to the belay loop or to the two tie-in points. But as a matter of comfort, it is preferable to attach your lanyard to the belay loop.”

So, sounds like the final recommendation from Petzl is the belay loop.

3 - Via Ferrata: use the belay loop

Standard practice in via ferrata is to girth hitch your tether carabiners to your belay loop. Keep in mind that a via ferrata fall can can generate tremendous force on your anchor system, harness and your body, greater than a factor 2.

Here's a diagram from Edelrid. The text accompanying this diagram reads: “Via Ferrata sets or systems with tie-in loops are fastened to the tie-in ring (belay loop) with a choke hitch (girth hitch).”

Here’s a similar diagram from Petzl. Clearly, Petzl recommends that via ferrata tethers go onto the belay loop.
